1.
2x 10 GBit/s DAC cables
2x EAP773 PoE
1x 2.5 Gbit/s copper
2.
Fan did spin up and down already at:
PoE Power Used
24.60W / 200.00W
3.
I feel previously the fans stayed low, now they spin up every few minutes and then spin down again to previous levels.
4/5
No other changes. I will rollback later this week and let you know if that changed the fan noise.

Hi @Acorny
Thanks for your information.
We tested locally, and the fan noise is the same as before.
If convenient, please use a noise measurement app to test the noise level when the fan spins up and down.
In the meantime, we will test more locally with a similar installation.

@Vincent-TP
Can confirm myself that the noise isn't measurably different, I am going to ascribe this to increased ambient temperatures. After testing there was indeed no difference between .19 and the most recent version. Apologies for reporting without testing other variables first.
edit: That said, I would love more control over fan curves and visibility into temperatures for the switch.

Hi @Acorny
Thank you for the update.
If you have any ideas about displaying temperature, you can join the discussion in this thread and cast your vote.

SNMP cable diagnostics is broken. OID 1.3.6.1.4.1.11863.6.8.1.3.2 always returns incorrect status and length, while .1.3.6.1.4.1.11863.6.8.1.2.1 returns correct values but not always. For example:
show cable-diagnostics interface gigabitEthernet 1/0/16
Port Pair Status Length Error Gi1/0/16 Pair-A Open --- 62 (+/- 2m) Pair-B Open --- 63 (+/- 2m) Pair-C Open --- 1 (+/- 2m) Pair-D Open --- 1 (+/- 2m)
SNMPv2-SMI::enterprises.11863.6.8.1.2.1.3.49168 = STRING: "---"
It is unclear how to obtain the value 62, which appears in the Error column. If I understand correctly, this is the distance at which the fault occurred. In older versions, the length, even when errors were present, was always available via SNMPv2-SMI::enterprises.11863.6.8.1.2.1.3.49168.

Hi @altlc
Thanks for the feedback.
Please let us know the model number, hardware version, and firmware version of the switch you are using. Thanks

Hi @altlc
Thanks for the reply.
One point prone to operation failure is that before walking the node 1.3.6.1.4.1.11863.6.8.1.3.2 (tpPortCableTestCFEntry), you must first perform a set operation on 1.3.6.1.4.1.11863.6.8.1.3.1 (tpPortCableTestFlush). “Flush” refers to refreshing the cable test results of the port, while 1.3.2 is used to read the refreshed results.
Please try executing the set 0 command on 1.3.1 and let us know the result.
After flushing, 1.3.2 uses CF cable test. For ports that are link up, the returned length is “–” instead of the actual length, which aligns with the results of show cable careful in standalone mode.
If the results from 1.2.1 are not always accurate, it might indicate a cable issue. Extremely short cables often cannot be detected correctly.
Please let us know the cable length, the cable test results, the link status (up/down), the speed, and the port number of the connected switch.

I know this procedure. We use SNMP for our monitoring system, and that’s exactly how it’s done: first 1.3.6.1.4.1.11863.6.8.1.3.1 – ports are turned on/off, then 1.3.6.1.4.1.11863.6.8.1.3.2 is read. Now the correct value is never there. It has also stopped working in the CLI:
